Description

Technical Field

[0001] This utility model relates to the field of instrument panel clamping technology, specifically to an instrument panel laser weakening clamping fixture. Background Technology

[0002] Currently, in the automotive manufacturing industry, an increasing number of car dashboards are equipped with airbags to minimize the fatality rate from traffic accidents. The surface skin of a car dashboard is generally made of materials such as PVC (Polyvinyl chloride polymer), TPO (Thermoplastic Polyolefin), and TPU (Thermoplastic Polyurethane), and is injection molded, with a thickness typically around 1.0–1.5 mm. Laser weakening involves making semi-permeable cuts on the inner surface of the injection-molded dashboard skin, leaving a certain residual thickness after the cut. The cut marks are not visible on the outer surface of the surface skin. The residual thickness varies depending on the design requirements of different car models and the elasticity and other physical properties of the skin material. The cut shape is generally a figure-eight. The precision of the residual thickness of the car dashboard surface skin is crucial to ensuring that the airbag can deploy within 0.08 seconds after inflation. Therefore, the tolerance requirements for the residual thickness are very strict; the internationally accepted standard controls the residual thickness within 1 ± 0.1 mm. However, when laser weakening airbag panels, the workpiece is directly gripped, resulting in inaccurate positioning. In addition, the size of the dashboard varies between different car models, and the same gripper can only correspond to one type of dashboard. Different grippers need to be changed when laser weakening different dashboards, which is costly and problematic. Utility Model Content

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0015] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features.
